Geant4 is a general purpose toolkit for the simulation of the passage of particles through matter. Primary focus of Geant4 was on preparation of experiments for CERN Large Hadron Collider. Other areas of application are growing and include high energy, nuclear and accelerator physics, studies in hadronic therapy, tomography, space dosimetry, and others. Geant4 physics includes different models for simulation of interactions of hadrons with nuclei.

The present web page contains nuclear data for the high precision transport model (G4NeutronHP) of neutrons with energies lower than 20 MeV. These data come from recent releases of the evaluated data libraries (e.g. ENDF/B_VII.0, JEFF-3.1, JENDL-4.0, etc), which have been converted into the Geant4 format. Such data are meant to replace the default G4NDL neutron library available with the standard Geant4 distribution. In this way, Geant4 users will have access to the complete list of standard evaluated neutron data libraries when performing Monte Carlo simulations with Geant4, have access to a larger list of isotopes and be able to estimate the systematic uncertainties in the results associated to the uncertainties in nuclear data.
